thank you so much, and that makes a lot of sense
Hi,
This doesn't sound at all like breast cancer to me,especially at your young age.You know,the skin of the breast is the same skin like on any other part on your body and the nipples/areolas are no exceptions,because they have sebaceous glands that can get clogged and form a pimple like lump,the same as clogged pores of the sweat glands in the face,forming a comedone,which is a blocked sweat gland due to dirt or skin debris.From what you have described,I think that the grey dots are blackheads caused by excess oils that have accumulated in the sebaceous gland's duct.You should refrain from squeezing them because you can make things worse and cause an infection.
You could apply warm compresses,use antibacterial soap and see if it goes away in a few days.If it doesn't,yes you should have your doctor or a dermatologist take a look at it,so you can get a professional evaluation and have this problem treated accordingly.
Take care...
